The four telemetry gaps (rows on commits, chord.host, microsecond times, a read-only store) and: pages record and
send span batches over their link to the server's ingest object (checked, capped, rate-limited, stamped browser and
with the link's principal); workers send theirs too, so the server is the store's only writer; principalAttributes
lets an app choose what a span records about its principal. The tutorial shows a real page's click traced to the
worker, with the trace viewer.
src/next is src (the main export), src/next-node is src/node with short subpaths (/http, /workers, /plugins,
/plugins/runtime, /app, /surfaces, /web, /react, /tui, /tui/launcher); the foundations get /json and /watch;
Chord v1 moves to src/old (/old, /old/node) until p2 runs on v2; tests and docs move likewise (test/, docs/,
test/old, docs/old). Durable and env import the foundations from their subpaths.
StoreStorage (Durable's storage on Chord v2's store, @earendil-works/pi-durable/storage/store) passes
Durable's storage conformance suite and runs Durable's harness tests (npm run test:store). The store
gets owner names and claims, one id allocator, Durable's Storage semantics for refused steps, history
none/latest/rewindable with reads at a point, archive revisions and applyBatch. self.follow follows
Durable's synchronous observers as Chord sources. Persisted jobs: records and state in the owner's
store, restarts as Durable's tasks, abort stored, deferred state. Chord's ./next export returns for
the adapter surface.
The Node driver takes the count from node:sqlite; the Durable Object driver reads
SELECT changes() after the statement, since the cursor's rowsWritten also counts
index writes (verified in workerd). run is unchanged and costs nothing more.
Reverts 48c8f3228 and 4759f09fb. Session sync replicates pi-durable commits instead of SQLite pages, so NodeSqliteDatabase.exclusive(), the replicated connection wrapper, the WAL reader, page checksums, the segment container, start-marker keys and the zstd page compressor have no user.
Portable modules under sqlite/replication: a WAL scanner that returns the newest page versions of committed transactions and stops at the last valid commit frame, incremental whole-database checksums from per-page hashes, the shared segment and base container with header validation, and object keys and start markers. A Node-only zstd page compressor sits beside them. None of it is exported from the package yet.
NodeSqliteDatabase.exclusive() runs an operation alone on the connection, outside a transaction, and rolls back a transaction the operation left open.
The internal replicated connection wrapper opens a database file with automatic checkpoints off, reports every operation, and runs a hook before SQLite checkpoints and deletes the WAL on close. It is not exported from the package yet.
